Phosphorous acid in the field of chemical production of raw materials in the safety of storage and transport specifications

1. Introduction

Phosphorous acid as an important chemical raw material, widely used in pesticides, pharmaceuticals, plastics, dyes and other fields. However, due to its unique chemical properties, phosphorous acid poses certain safety risks during storage and transportation. In order to ensure production safety and reduce the probability of accidents, it is very important to formulate a set of strict phosphorous acid storage and transportation regulations.

2. the properties and hazards of phosphorous acid

phosphorous acid is a colorless transparent liquid with a pungent odor. Its vapor has a stimulating effect on the eyes, skin and respiratory system, and can cause burns, coughing, difficulty breathing and other symptoms after contact. Long-term exposure to phosphorous acid vapor may lead to chronic poisoning, neurasthenia, abnormal liver function and other symptoms. In addition, phosphorous acid is also corrosive and has a certain destructive effect on metal containers and pipes.

3. Phosphorous Acid Storage Specification

1. The storage place should choose a cool, ventilated and dry place, away from fire, heat and direct sunlight.
2. The storage container shall be made of special corrosion resistant materials, such as polyethylene and polypropylene, and the integrity of the container shall be checked regularly.
3. The storage area shall be equipped with leakage emergency treatment equipment, such as adsorption material, neutralizing agent, etc., to deal with possible leakage accidents.
4. Storage personnel should be professionally trained to understand the nature of phosphorous acid and safe operating procedures, and conduct regular physical examinations to ensure good health.

4. of phosphorous acid transport specification

1. Transport vehicles should have the appropriate qualifications and certificates, transport personnel should be professionally trained to understand the nature of phosphorous acid and safe operation procedures.
2. During transportation, it should maintain a smooth driving, avoid violent vibration and collision, and prevent the packaging container from being damaged.
3. Transportation vehicles shall be equipped with corresponding emergency treatment equipment, such as leakage treatment tools, fire fighting equipment, etc., to deal with possible leakage accidents.
4. During transportation, relevant laws, regulations and standards shall be observed to ensure transportation safety.

5. emergency treatment measures

1. In case of phosphorous acid leakage accident, the emergency plan shall be started immediately and professionals shall be organized to deal with it.
2. Use special absorbent materials to clean up the leakage and avoid flowing into sewers or drains.
3. Ventilate the contaminated area to ensure air circulation.
4. If contact with phosphorous acid causes burns or poisoning symptoms, the patient should be immediately moved to a safe area, take appropriate first aid measures, and promptly sent to the hospital for treatment.

6. conclusion

phosphorous acid as an important chemical raw material, there are certain safety risks in the process of storage and transportation. In order to ensure production safety and reduce the probability of accidents, the corresponding storage and transportation specifications must be strictly observed. By strengthening the training of management personnel, regular maintenance of storage equipment, compliance with transportation regulations and other measures, the safe use of phosphorous acid in the field of chemical production raw materials can be ensured.
